While this device is described as being A urticuluriy wcli :idnpted for handling:r heut/'y lubricating; oil nudgrcuse it will he understood that the suine may be used for handling other Viscous substances.

F rom the foregoing descrii'ition taken in connection with the accompanying druivings the :idvontuges of the construction und of the method or" operation of my grouse gun wili he readily apparent, but, while I have described the principle of operation of the invention together with the device I now consider to he the host embodiment thereof it will he understood that the structure shown is merely illustrative und that such changes muy be mode :is nre within the scope of the 'following claim.

What I. claim is grease gun comprising,r n receptacle, u piston freely movable within scid rcccptucle. conduit connected with euch end o1" said receptacle, o discharge nozzie connected with one of seid conduits, ineens for admitting' grease under pressure to the other conduit', :i threeovuy vulve interposed in euch of said conduits` n oy poss conduit connected with the lowcrmost three-wey rulve und with the uppermost conduit at :i point above the Auppermost threewny valve und. unothe;` by

pass conduit connected with' the uppermost threeivuy vulve und with thc loirermost conduit :it :1 point helov.' the lowermost three- Wuy vulve.

in Witness whereof. hereunto subscribe my nume this 27th doy of h'l'uroh, D. 1920.
